Just to test posibilities I used the EM editor to insert the code of other into question as this

{INSERTANS:12813X1X2other}

What I get:
While in question the replacement shows the value inserted in the textfield of other, in the response the same expression shows just text "Other:".
With the normal responses SGQA identifier works (the SGQ identifier doesn't).

For illustration of the issue please see the screenshot below.

What am I missing? Why I don't get the other content in the possible response?

Picture explanation: The answer to question empl_qt was other/8. In question you can see number 8. While in possible answer is "Other:".

PS: LimeSurvey somehow detected that my native language is Czech, so it translates everything in Czech. So in this question I retranslated all back to English. I'm sorry if I translated something wrong.
